Show QR code

Show a QR code for the different links so that mobile devices can become peers without users having to type in the URL.

I can give this a go if it's wanted.

I only use instant.io occasionally, so don't feel obliged to do this for my sake. I do think that this feature would be very handy though.

@joshterrill Yeah, that would be cool to try. But are there any good QR reading libraries in pure javascript? I've seen tons of QR code generators, but only a few that can take grainy images from a webcam and parse the QR codes out of them.

[joshterrill]

I'll look around and post what I find before I really start digging into it.

@feross I found just https://github.com/LazarSoft/jsqrcode, do you know any other qr reading in js?

[xxxorg]

Would you accept PR just for the qr code generation (not the reading)?

[joshterrill]

@xxxorg I don't think we need it to read... I think it's just QR code generation so that a mobile app who has a reader can scan it. Am I right?

[feross]

I would accept a PR just for generation for now. We can figure out reading
later.

I can recommend http://neocotic.com/qr.js/ for QR generation which I have been using for years in a web application.

I just wrote this yesterday but forgot to commit it. I'll do it later today.

As for qrcode generation there is also https://larsjung.de/kjua/. It works without jQuery and is very powerful. (alternatively this works with jQuery)
